My grateful thanks for the wealth of information and assistance offered by Rolf Dessauer, Dave Gants, Tomas Stohr and Bob Allison (those websites are wonderful). I hope to try both the Dylux and digital camera methods--- both techniques quite new to me, but less likely to panic our physicists than my old radio-active source method (which was like working in a deep-sea diving suit anyway). Do the rest of you using beta-radiography go though this? (I used to wave a u.v. lamp around quite happily, too, until they insisted on kitting me out with visors, gloves, tongs and heaven knows what-all.) What a splendid List!
